EXCLUSIVE

It was over a year in the making -- but Buzz Aldrin's bitter divorce from wife #3 is finally official ... and she's making off like a bandit.

The divorce order was signed just three days after Christmas -- and according to the docs, Buzz' ex-wife Lois Driggs Cannon gets pretty much half his fortune ... including 50% of a $475,000 bank account, and 50% of the profits from his businesses, trademarks, and stocks.
